`Theoperation of the above described machine consists first in placing the foot on the lever (No. 12), raising the post (No. 11) y until it comes in contact with Ithe face plate (No. 3) retaining `the different pieces of the barrel head in a proper position until by the operation of the hand-wheel the projecting points of the center bearing springs are brought in contact with the different pieces `forming the barrel head pressing them firmly against the plane surface of the driving face plate (No. 3). By this pressure, pieces of different thickness may be cut at the same timethe springs yielding readily to the thicker portions of the material. The only form of cutters used with success is the right, or one cutting the inner circle and `bevel inthe form of a gougeand the left,

or one cutting the outer circle and bevel of the barrel hea-d in the `form of a V. Any sizedbarrel'head required maybe cut by this machine from 16 to 24 inches in diameter, by withdrawing the rest. A long or short bevel may be given by enlarging or contract-- ing `the distance between the rests at the outer end; Vthe cutting being done from the center toward the circumference, bringing the operation of the cutter upon the chip in! stead of upon the solid portion of the barrel head. The average number of heads cut by `this machine, by one man, in ten hours is 800.

Your.Y petitioner hereby enters his dis-` i `claimer to all or any portions of the machine aforesaid,for which a patent or patents may have been granted previous to the tiling of this petition. Y y `What I claim as my invention and desire to secure by Letters Patent, is-
